There are also many non-celiacs who would swear that they cannot eat glutten. That does not discredit the actual existence of celiacs.

When I was younger, I would sometimes discover that certain foods contain MSG by identifying what I had eaten before the onset of symptoms. Now I've learned to check everything beforehand. And the one time that the mother-in-law used her neighbour's soup mix instead of the soup mix that I bought her, I was able to know by the symptoms. Now my teenagers avoid MSG, but not because they are sensitive. The older of them is a vegetarian, but not because she lacks incisors or canines.

But coeliacs disease is a real thing, whereas there is no evidence that MSG sensitivity is, so they are not comparable.

Of course there is evidence, that is why we are having this discussion. In addition to the evidence that there exists a very small minority of people who are sensitive to MSG, there exists a large industry that is dependent upon the availability of an inexpensive, effective flavour enhancer. That industry has an interest in discrediting the ill effects of MSG, just as the petrochemical industry had an interest in discrediting the effects of CO2 in the atmosphere and the tobacco industry had an interest in discrediting the effects of smoking.

I must be mistaken because based on the article, I thought we were having this discussion because there is no evidence.

[dotancohen]

The article mentions right in the beginning that studies have shown evidence for a connection between MSG intake and onset of symptoms.

MSG occurs naturally in a lot of foods and won't necessarily show up in ingredient lists. It's in tomatoes, soy sauce, seaweed, etc.
